RE: Which Linux??

Since Ubuntu is a Debian-based distribution, you'll need to "fix" some stuff before running the installer, and you'll need to run with the -ignoreSysPreReqs option. If you do a Google search for "oracle on ubuntu 7.10", you get lots of hits.

But, it does not work on the Dell Vostro 200 desktops. CentOS 4/5 does not have the drivers (I believe) for the new SATA in Vostro and I couldn't get to install... at the moment it seems to me ubuntu is the only choice.

I am thinking of running at 10/11g on a FREE Linux. I know the amount of patches you need to stabilise Oracle and get it running can be an issue, SO . . .Of the many flavours out there, which do you consider the best and most stable? I've used Solaris and HP-UX for many years, so know my way around UNIX well.
